Navy technical aptitude

About this practice suite

This suite prepares candidates for navy technical aptitude selection in the military and defence sector with 5 skill areas: mechanical comprehension, numerical reasoning, technical reasoning, data interpretation and safety judgment. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Mechanical comprehension — Forces, motion, gears, pulleys, levers, fluids, pressure, and basic machines.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Data interpretation — Tables, charts, graphs, dashboards, trends, comparisons, and evidence-based conclusions.
• Safety judgment — Hazard recognition, safe sequencing, escalation, and risk controls.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

1. A ship's draft increases when it:

   • A. Reduces water density
   • B. Empties fuel tanks
   • C. Loads more cargo
   • D. Raises its mast

2. Hydraulic fluid transmits force mainly because liquids are:

   • A. Unable to flow under pressure
   • B. Always lighter than air
   • C. Self-lubricating only by colour
   • D. Nearly incompressible in closed systems

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
